To all whom it may concern: Be it known that 1, PAUL PAGAC, .a citizen of the United States, residing at Chicago, in the county'of Cook and State of Illinois,

have invented certain new and useful Improvements in Attachments for Sewing Machines. 1

This invention relates to attachments for sewing machines. It is a common complaint in shops using a number of sewing machines, inschoo1s for teaching the making. of clothes and the like arts, and in other such establishments,that a great deal of time is lost by the i Y clianging of spools from one color of thread 5 to another when working on various colors of material.

It is a still further complaint that theft of thread and spools is very common and amounts to a very largeaggregate. Therefore, the invention has for one of its principal objects. the provision of a device for holding a plurality of spools of thread in such a position that any one of them. may be used without removing the others from the machine.

Another important object is to provide such an attachment made to .fit any standard sewing machine without necessitating any change in the structure of the machine.

0- Another important object is to provide 7 means for locking the spools of thread upon. the machine so as to prevent theft thereof.

Another object is to provide an attachment which may be readily removed from a machine, if desired.

A still-further object is to devise an attachment which will he inexpensive to manufacture. I Y

Other objects will be in part apparent and in part pointed out in the course of the descrlption.

Referring now ,to the drawings forming a part of this specification, Y

Fig. 1 is a view'in elevation of a head of a sewing machine'with-my attachment thereon. v

Fig. 2 is a plan view of my attachment in place. v

Fig. 3 is a view partly in section on'the line 3-3 of Fig. 2. V

The num r l 1 d signa es a conventiona m y b re d y pl d on or removed head for a sewing machine of any standard make. Such heads commonly have an aperture-2 in thetop thereof to receive a pin on which is usually mounted a spool of thread, and at the other end thereof means for stitching, indicated generally at 3. Mounted upon the top of the head is my improved attachment which consists essentially of a metal plate 4 having mounted therein by any suitable means, as by screw threads 5, a plurality of pins 6. The plate 4 isattached to the head at one end by a link 7 having 3 one end 8 pivotally mounted in the plate 4 and having the other end 9 occupying the aperture 2 in the head 1, the pin usually occupying this aperture having been removed. The other end of the plate et'is attached to the head by means of a clamp 10, embracing the head as shown, and adapted to be tightened thereon by any suitable means, as by a bolt 11, as plainly shown in Fig. 3. The pins 6 are of such a size and are so spacedas to support a plurality of spools of thread, and

at their upper ends, at a height sufficient to clear the spools, these pins are apertured as at '12, the apertures 12 being in alignment and receiving a slidablelocking bar 13. The locking bar has one end enlarged as at 14 to prevent passage through the pins 6, and its so I other end has suitable locking means thereon, in this embodiment, said locking means being exemplified by an aperture 15, receiving a padlock 16. It will be noted that the link 7 will permit adjustment of the entire attachment so that the central line of the attachment may be placed at an angle to the lon itudinal center line of the machine head 1. means of thisarrangement, it will bereadi y seen that thread may be unwound I from any of the spools "and led to the stitching means 3.

In the embodiment. illustrated, I have shown five pins 6' and locking means to keep the spools on four of the pins. I prefer this construction because it permits the use of a number of thespools of colors which are commonlyiused and those s 001s are locked in place. I-prefer to leave t e one pin 6- unlocked so that a spool of thread of some special color, which 18 only used occasionally,

from

without involving any change in the struc:

ture of the machine other than the removal of a small pin, which removal is easily effected.

The bolt 11 is reduced for a portion of its length, as' shown at 18, and this portion may be-round, square, or of any othersuitable shape, whereby when it'is engaged by the pint, the bolt 11' will be locked against removal. Means is thus provided for locking the entire attachment to the sewing machine. When the attachment'is to placed on the machine, the clamp 10 is first put in place, the bolt 11 is then passed through the .'openings in the'upper ends and threaded through the block 17. The link 7 of the plate 4 is then placed in position with its end 9 in the aperture 2, the pin 6 is passed through its opening in the plate 4 and screwed tightly into the block 17. lhe

spools are then placed in position on the pins 6, 6' and 6", the locking bar 13 is passed. through the aligned opening 12 in the pins, and the padlock l6 placed in posi- I tion. It will thus be seen that the attachment is securely locked to the sewing machine, and can not be removed therefrom Without first removing the padlock 16.

It will befurther apparent that my attachment is cheaply made and will eflectively support a plurality of spools of thread in such a position that thread may be unwound from any, one for use in the machine, and that as many spools as desired may be effectively locked in position to prevent theft.

I am aware that changesin the form and proportion of parts in details of construction of my invention may be made Without departing from the spirit or sacrificing the advantages of the invention, and, therefore I reserve the right to make all such changes as fairly fall within the scope of the follow-' ing claims; for example, it is obvious that the locking bar 13 may be made to lock as many or as few spools as is desirable and that any other locking means may be substituted for the padlock 16 and bar 13.

I claim: 1. An attachment for sewing machines comprising a member adapted to be clamped at one end to a sewing machine head and adjustably mounted at the other end to said head-whereby said attachment may be disposed at an angle to said head for the purpose set forth.

2. An attachment for sewing machines comprising a plate, a clamp atone end of said plate, a link at the other end of said plate, and spool supporting means on said plate.
